Application filed January 23, 1902. Serial No. 90,868. (No model.)

To all whom it may concern: mounted to turn in ahalf-bearing H, securedBe it known that I, HARVEY EUGENE BAE- to one end of the tank A, and theother head TON, a citizen of the United States, and a resi- D isprovided with a polygonal offset G, fitdent of Attleboro, in the countyof Bristol ting into a correspondingly-shaped head I, 55 and State ofMassachusetts, have invented a attached to one end of a shaft I, mountedto new and Improved Tumbling Machine, of turn in a bearing H, secured tothe other end which the following is a full, clear, and exact of thetank A directly opposite the bearing H. description. On the outer end ofthe shaft I are secured The object of the invention is to provide a thefast and loose pulleysJ and J, connected 6o 10 new and improvedtumbling-machine which by belt with other machinery for imparting issimple and durable in construction, very a rotarymotion to the saidshaft I and by the effective in operation, and more especially dehead Iand offset G to the barrel B. signed for treating jewelry-such aschains, The device is used as follows: The tank A parts thereof, and thelike-to clean and polis filled with a cleansing solution, asindicated 65ish the same in a veryinexpensive and thorin Fig. 1, and the jewelry tobe treated is ough manner. placed in the barrel B at the time the latterThe invention consists of novel features is removed from the tank andthe head D and parts and combinations of the same, as has been opened.When the jewelry has will be more fully described hereinafter and beenplaced in position in the barrel, then the 70 then pointed out in theclaims. head D is moved in place, and then the bar- A practicalembodiment of the invention rel is engaged by its offset G with the headI, is representedin the accompanying drawings, and the trunnion G isdropped into the bearforming a part of this specification, in which ingH.

The barrel-head D is The head D is provided with a trunnion G,then opened and the clean jewelry is rel moved, and other jewelry to betreated is placed in the barrel, and then the above-described operationis repeated.

The solution and the impurities in the tank can be drawn off therefromwhenever desired by a suitable draw-off cock K. (Shown in Fig. 1.) Thesolution in the tank is preferably heated by the use of a steam-pipe L,connected'with a boiler and extending into the tank A and beneath thebarrel B.

By the use of this machine many articles, such as Watch-chain swivelsand the like, are finishedto such a degree that the usual subsequentprocess of burnishing can be entirely dispensed with. It will also benoticed that by the constant agitation of the articles under treatmentit requires but a short time to remove extraneous matter.-

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A tumbling-machine, comprising a tank forcontaining a cleansing solution, and a tumbling barrel mounted torevolve in the tank, said barrel having one of its heads removable andprovided with longitudinal ribs on its inner surface and withscreen-covered openings in its head, as set forth.

2. A tumbling-machine, comprising a tank for containing a cleansingsolution, and a tumbling barrel mounted to revolve in the tank, saidbarrel tapering from its center toward each end, having one of its headsremovable, and provided with a screen-covered opening in its heads andwith longitudinal half-round ribs on its inner surface, as set forth.

3. Atumbling-machine comprising a tank for containing a cleansingsolution, a revoluble tumbling barrel formed at the inner faces of thestaves with ribs, and provided in its heads with screened openings, oneof the heads being removable, and means for rotating the barrel, thelatter having a removable connection with the said means, as set forth.

4:. A tumbling-machine, comprising a tank for containing a cleansingliquid, and a revoluble tumbling barrel removably mounted in the tank,said barrel having a removable head and provided with openings for thecirculation of the liquid in the tank, and with means on the innersurface for raising the articles and then dropping them into thesolution, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
